본 발명은 지열회수를 통한 통합 보일러 시스템에 관한 것으로, 더욱 상세하게는 지하 깊은 곳으로부터 지열을 회수하여 이 열을 통해 급탕탱크 내부의 급탕수를 가열해주도록 하고, 이러한 급탕수를 직접 배출시키거나 개별보일러로 공급해줌으로써 개별보일러의 연료 소모량을 절감할 수 있도록 한 것이다.The present invention relates to an integrated boiler system through geothermal recovery, and more particularly, to recover the geothermal heat from the deep underground to heat the hot water in the hot water tank through this heat, and to discharge the hot water directly By supplying individual boilers, the fuel consumption of individual boilers can be reduced.

주지하다시피, 아파트와 같은 공동주택에는 큰 크기의 중온수보일러를 통해 물을 가열하여 이를 각 세대별로 공급해주는 중앙난방 시스템과, 각 세대별로 각각 개별보일러가 설치되어 이를 통해 각 세대별로 개별적인 난방을 하는 개별난방 시스템의 2가지 방식 중 어느 하나의 방식이 적용되어 난방 및 급탕기능을 수행하고 있다.As is well known, apartment houses such as apartments have a central heating system that heats water through a large-sized hot water boiler and supplies it to each household, and individual boilers are installed for each household to provide individual heating for each household. Any one of the two methods of the individual heating system is applied to perform the heating and hot water supply function.

이 중 중앙난방 시스템은 모든 세대별로 동일한 온도를 갖는 물을 공급해주게 되므로 관리가 용이한 이점은 있으나, 사람마다 취향이 다르고 자신이 원하는 시간에 난방을 할 수 없는 단점이 있어 개별난방 시스템을 더 선호하는 경향이 있다.Among them, the central heating system provides water with the same temperature for all households, so it is easy to manage, but individual heating systems are preferred because they have different tastes and cannot be heated at the time they want. Tend to.

그러나, 이러한 개별난방 시스템의 경우 급탕만 필요하고 난방은 필요없는 하절기와 같은 계절에도 급탕을 구현하기 위해서는 개별보일러를 가동해야만 하므로 연료 소모가 많은 단점이 있었다.However, such an individual heating system has a disadvantage in that fuel consumption is high because the individual boiler must be operated to implement the hot water supply in a season such as summer, which requires only hot water supply and does not need heating.

본 발명은 이러한 점에 착안하여 안출한 것으로, 지중으로부터 지열을 회수하여 이를 히트펌프의 증발기측 냉매관과 열교환기에서 열교환하도록 하고, 급탕수 가 채워지는 급탕탱크-히트펌프의 응축기-급탕탱크 순으로 급탕수가 순환되도록 급탕가열관을 연결하여 급탕탱크 내부의 물을 히트펌프의 응축기로부터 발생되는 열에 의해 가열해주도록 하며, 급탕탱크와 연결된 급탕공급관은 각 세대별 개별보일러의 급탕용 급수측에 연결하면서 급탕공급관으로부터 분지된 분지관은 개별보일러로부터 인출된 급탕관에 연결하며, 급탕공급관, 분지관, 급탕관에는 각각 단속밸브를 구비함으로써 기본적으로 개별보일러를 사용하면서 계절에 맞게 단속밸브를 개폐하여 급탕탱크에서 예열된 급탕수가 직접 수도밸브로 배출되게 하거나, 개별보일러로 유입되도록 함으로써 연료비를 절감함과 동시에 사용상 편의성을 도모할 수 있는 지열회수를 통한 통합 보일러 시스템을 제공하고자 하는 것이다.The present invention has been made in view of this point, the ground heat is recovered from the ground to heat exchange in the refrigerant pipe and the heat exchanger on the evaporator side of the heat pump, the hot water supply tank is filled with condenser-water supply tank Connect the hot water heating tube so that the hot water is circulated to heat the water in the hot water tank by the heat generated from the condenser of the heat pump, and the hot water supply pipe connected to the hot water tank is connected to the hot water supply side of the individual boiler for each household. While the branch pipe branched from the hot water supply pipe is connected to the hot water pipe drawn from the individual boiler, the hot water supply pipe, the branch pipe, and the hot water pipe are provided with an intermittent valve, respectively, basically using the individual boiler to open and close the intermittent valve according to the season. Allow the preheated hot water from the hot water tank to be discharged directly to the water valve or to the individual boiler While also reducing fuel costs by making and seeks to provide an integrated system with a geothermal heat recovery boilers to achieve the ease of usability.

이때, 도시하지는 않았지만 급탕공급관(42)과 급탕관(60)은 개별보일러(80)의 내부에서 서로 연결되며, 급탕탱크(40)는 아파트 단지의 보일러실과 같이 중앙관리가 용이한 위치에 설치하게 되고, 개별보일러(80)는 각 세대별로 설치함은 자명하다.At this time, although not shown, the hot water supply pipe 42 and the hot water supply pipe 60 are connected to each other in the interior of the individual boiler 80, the hot water supply tank 40 to be installed in a location that is easy to central management, such as the boiler room of the apartment complex It is apparent that the individual boiler 80 is installed for each household.

또한, 지중열교환기(20)는 지하 30∼50m까지 직립되게 세워지는 식립관(22)과, 식립관(22)의 단부로부터 지하 400∼450m까지 뚫리는 지중열회수공간(23)과, 일단부는 식립관(22)을 통해 지중열회수공간(23)의 아래쪽까지 삽입되고 타단부는 지중열회수열교환기(30)를 거쳐 식립관(22)의 상부에 위치된 지중열이송관(21)과, 지중열이송관(21)의 식립관 내부위치 일측에 연결되어 지중열회수공간(23)에 있는 물을 펌핑해주는 워터펌프(24)로 구성된다.In addition, the underground heat exchanger (20) is an implantation pipe (22) which is erected upright to 30 to 50m underground, an underground heat recovery space (23) which is drilled from the end of the implantation pipe (22) to 400 to 450m underground, and one end is implanted.

이와 같이 구성된 본 발명에 따른 지열회수를 통한 급탕수 공급시스템은 다음과 같은 작용을 한다.The hot water supply system through the geothermal recovery according to the present invention configured as described above serves as follows.

일반적으로 지하 15m 이하의 공간은 연중 온도변화가 거의 없으며, 지하 400∼450m 지점의 온도는 연장 15∼20℃를 유지하게 된다.Generally, the space below 15m underground has little temperature change throughout the year, and the temperature of 400 ~ 450m underground is maintained at an extension of 15-20 ℃.

또한, 지표면으로부터 지하 30∼50m까지는 표사층을 이루고, 이후부터는 암반층을 이루게 되며, 지하수가 표사층의 중간부에서 그 수위를 항상 유지하고 있다.In addition, the surface layer forms a sand layer from 30 to 50 m below the ground surface, and subsequently forms a rock layer, and the groundwater always maintains its level in the middle part of the surface layer.

본 발명은 지하 400∼450m에 위치하고 있는 따뜻한 물로부터 지중열을 회수하여 이를 통해 급탕수를 가열하고, 이 급탕수를 개별보일러 시스템에 공급하도록 한 것으로, 지중열교환기(20)는 그 식립관(22)을 표사층으로 된 지하 30∼50m까지 만 박을 수 있으며, 표사층 밑에 위치하는 암반층부터는 식립관(22) 내부로 드릴과 같은 굴착장비를 투입하여 지표면으로부터 400∼450m까지 지중열회수공간(23)을 굴착하게 되고, 이후 굴착장비를 제거하고 지중열이송관(21)을 지중열회수공간(23)의 저부까지 삽입하여 구성하면 된다.The present invention is to recover the ground heat from the warm water located in the basement 400 ~ 450m to heat the hot water supply, and to supply the hot water to the individual boiler system, the underground heat exchanger 20 is the installation pipe ( 22) can be built up to 30-50m underground with the surface layer, and from the rock layer located beneath the surface layer, drilling equipment such as a drill is inserted into the placement pipe 22 to the ground heat recovery space from 400 to 450m from the ground surface ( 23) is excavated, and then the excavation equipment is removed and the underground heat transfer pipe 21 is inserted into the bottom of the underground heat recovery space 23.

이러한 상태에서 전원을 공급하여 히트펌프(10)를 가동함과 동시에 지중열교환기(20)의 워터펌프(24)를 구동하게 되면 지중열이송관(21)을 통해 지하 400∼450m에 있는 15∼20℃의 따뜻한 물이 상승하여 지중열회수열교환기(30)측으로 이송되며, 지중열회수열교환기(30)에서는 냉수가 유동하는 냉수관(31)과 지중열을 포함한 따뜻한 물이 유동하는 지중열이송관(21)이 열교환하도록 구성되어 있어 지중열이송관(21) 내부로 유동하는 지중열을 포함한 따뜻한 물은 냉수관(31)의 냉수와 열교환하는 과정에서 온도를 빼앗겨 차가워진 상태로 다시 식립관(22)의 상부로 배출되고, 냉수관(31) 내부를 유동하는 냉수는 지중열을 포함한 물로부터 열을 빼앗아 온도가 상승된 상태로 히트펌프(10)의 증발기(14)측으로 유동된다.In this state, when power is supplied to operate the heat pump 10 and drive the water pump 24 of the underground heat exchanger 20, the ground heat transfer pipe 21 may be used to provide 15 to 15 m in the underground 400 to 450 m. Warm water of 20 ℃ rises and is transported to the ground heat recovery heat exchanger (30) side, the ground heat recovery heat exchanger (30) is a cold water pipe (31) through which cold water flows and underground heat transfer pipe through which warm water including ground heat flows (21) is configured to exchange heat, so that the warm water including the geothermal heat flowing into the underground heat transfer pipe (21) in the process of heat exchange with the cold water of the cold water pipe (31), the temperature is taken down and placed again in the cold state ( The cold water discharged to the upper portion of 22) and flowing inside the cold water pipe 31 is flowed to the evaporator 14 side of the heat pump 10 in a state in which the temperature is increased by taking heat from water including underground heat.

식립관(22) 상부로 다시 차가워진 상태의 물이 유입되더라도 식립관(22)의 수위는 항상 일정하게 유지되며, 이러한 차가워진 상태의 물은 다른 따뜻한 물과 희석되어 다시 온도가 따뜻해지고, 또 펌핑이 지하 400∼450m에서 이루어지게 되므로 지중열이송관(21)을 통해 이송되는 물은 항상 온도가 일정하게 된다.Even if the water in the cold state is introduced into the upper part of the insertion tube 22, the level of the insertion tube 22 is always kept constant, and the water in this cold state is diluted with other warm water to warm the temperature again, and Since pumping is made in the basement 400 ~ 450m water is transferred through the underground heat transfer pipe 21 is always a constant temperature.

히트펌프(10)의 증발기(14)에서는 그 냉매관 내부의 냉매가 냉수관(31) 내부의 냉수로부터 열기를 빼앗아 증발될 수 있고, 냉수관(31)의 냉수는 다시 차가워진 상태로 지중열회수열교환기(30)측으로 유동하게 되며, 이러한 과정을 반복하게 된 다.In the evaporator 14 of the heat pump 10, the refrigerant inside the refrigerant pipe can be evaporated by taking heat from the cold water inside the cold water pipe 31, and the cold water in the cold water pipe 31 is cooled again to the ground heat recovery. It will flow to the heat exchanger 30 side, this process is repeated.

히트펌프(10)의 증발기(14)에서 온도를 빼앗아 증발된 냉매는 이후 압축기(11)를 거쳐 고온고압의 상태로 압축되어 응축기(12)로 들어가게 되고, 응축기(12)에서는 그 냉매관 내부의 고온고압 상태의 냉매가 급탕가열관(50) 내부의 급탕수와 열교환하는 과정에서 온도가 내려간 상태로 팽창밸브(13)를 거쳐 증발기(14)로 순환하는 과정을 반복하게 되고, 급탕가열관(50)의 급탕수는 냉매로부터 온도를 빼앗아 다시 급탕탱크(40)로 유입되는 것이다.The refrigerant evaporated by taking the temperature from the evaporator 14 of the heat pump 10 is then compressed into a state of high temperature and high pressure through the compressor 11 to enter the condenser 12, and in the condenser 12, The refrigerant in the high temperature and high pressure state is circulated to the evaporator 14 through the expansion valve 13 while the temperature is lowered in the process of heat exchange with the hot water in the hot water heating tube 50, the hot water heating tube ( The hot water of 50) takes the temperature from the refrigerant and flows back into the hot water tank 40.

이때, 급탕가열관(50)은 급탕탱크(40) 내하부의 새로운 물을 히트펌프(10)측으로 순환시켰다가 열을 얻은 후 급탕탱크(40)의 중간부로 다시 공급하는 과정을 지속적으로 반복하게 되므로 급탕탱크(40) 내부에 채워진 물은 지속적으로 열기가 축적되어 뜨겁게 가열되는 것이다.At this time, the hot water heating tube 50 continually repeats the process of circulating new water in the lower part of the hot water tank 40 to the heat pump 10 and then supplying heat to the middle part of the hot water tank 40 again. Therefore, the water filled in the hot water supply tank 40 is that heat is continuously accumulated and heated hot.

급탕탱크(40) 내부에서 지속적으로 예열된 급탕수는 급수구(41)를 통해 물이 공급됨과 동시에 그 압력에 의해 급탕탱크(40) 상단부에 연결된 급탕공급관(42)을 통해 이동하게 되는데, 하절기의 경우 난방을 하지 않고 급탕만 약간 필요하게 되므로 급탕관(60)과 급탕공급관(42)에 설치된 단속밸브(43)(61)를 잠그고, 분지관(90)에 설치된 단속밸브(91)만 열어주어 급탕수를 수도밸브(70)로 직접 배출시킬 수 있도록 하며, 동절기의 경우 난방을 실시함은 물론 급탕탱크(40)에 의해 예열되는 온도만으로는 충분히 뜨거운 물을 공급할 수 없으므로 급탕관(60)과 급탕공급관(42)에 설치된 단속밸브(43)(61)는 열어주고, 분지관(90)에 설치된 단속밸브(91)는 잠가주어 급탕수가 개별보일러(80)의 내부로 이동하도록 하는 것이다.The hot water continuously preheated in the hot water tank 40 is supplied with water through the water inlet 41 and moves through the hot water supply pipe 42 connected to the upper end of the hot water tank 40 by the pressure. In this case, only a hot water supply is required without heating, so the intermittent valves 43 and 61 installed in the hot water supply pipe 60 and the hot water supply pipe 42 are closed, and only the intermittent valve 91 installed in the branch pipe 90 is opened. Given that the hot water can be discharged directly to the water valve (70), in the case of winter, as well as heating the hot water supply only by the temperature preheated by the hot water tank (40) hot water supply pipe (60) and The intermittent valves 43 and 61 installed in the hot water supply pipe 42 are opened, and the intermittent valve 91 installed in the branch pipe 90 is locked to allow the hot water to move into the individual boiler 80.

이와 같이 개별보일러(80)로 급탕수가 유입되면 급탕수 자체가 이미 예열되어 있으므로 개별보일러(80)를 통해 원하는 온도만큼 급탕수의 온도를 올려줄 때 그 가열시간을 절약할 수 있으므로 결과적으로 연료비를 절감할 수 있는 것이다.In this way, when the hot water is introduced into the individual boiler 80, since the hot water itself is already preheated, the heating time can be saved when the temperature of the hot water is increased by the desired temperature through the individual boiler 80, resulting in fuel costs. You can save.

이때, 본 발명에 적용되는 단속밸브(43)(61)(91)는 일반적인 볼밸브를 사용하여 수동으로 제어할 수도 있으며, 또한 도면상에 도시하지는 않았지만 급탕공급관(42)의 일측에 온도센서를 설치하고, 단속밸브(43)(61)(91)를 전기적인 신호를 통해 제어가 가능한 솔레노이드 밸브로 구성하여 급탕탱크(40)에서 예열된 급탕수의 온도가 일정온도 이하이거나 이상이면 자동으로 솔레노이드 밸브를 단속하여 급탕수를 개별보일러(80)측으로 또는 수도밸브(70)측으로 이동시킬 수 있고, 이와 함께 개별보일러(80)를 자동으로 온/오프시킬 수도 있는 것이다.At this time, the control valve 43, 61, 91 applied to the present invention may be manually controlled using a general ball valve, and although not shown in the drawing, a temperature sensor is provided on one side of the hot water supply pipe 42. And the solenoid valve 43, 61, 91 can be controlled by an electrical signal so that the solenoid is automatically heated when the temperature of the hot water supplied to the hot water tank 40 is below or above a predetermined temperature. By intermittently controlling the valve, the hot water can be moved to the individual boiler 80 side or the water valve 70 side, and the individual boiler 80 can be automatically turned on / off.

그리고, 설명하지는 않았지만 개별보일러를 통한 각 세대별 난방은 일반적인 것과 동일하게 이루어지게 된다.And, although not described, the heating for each generation through the individual boiler is made the same as the general.

이상에서 설명한 바와 같이, 본 발명은 지중열을 회수하여 히트펌프의 냉동사이클을 순환시키고, 히트펌프의 다른 곳에서 열기를 다시 회수하여 급탕탱크 내부에 지속적으로 축적함으로써 급탕탱크에 채워진 급탕수를 지속적으로 가열할 수 있는 것이므로 급탕수를 가열하는데 연료의 소모가 전혀 없으며, 이러한 급탕수를 계절에 따라 수도밸브로 직접 배출되게 하거나 개별보일러로 유입시키도록 한 것이므로 사용상 편의성을 도모할 수 있고, 개별보일러의 가스 소모량을 절감할 수 있으며, 급탕탱크에 의해 예열된 상태의 급탕수가 급탕공급관이나 분지관을 통해 유 동하게 되므로 차가운 물에 비해 예열된 물의 용존산소량이 적어 관의 부식속도를 저하시킬 수 있고, 수도밸브를 통해 물의 배출시 초기부터 따뜻한 물이 공급될 수 있어 기존 개별보일러만으로 급탕을 공급할 때 초기 따뜻해질 때까지 차가운 물을 모두 버리는 것에 비해 물을 절약할 수 있는 효과도 있는 것이다.As described above, the present invention is to recover the ground heat to circulate the refrigeration cycle of the heat pump, to recover the heat from other places of the heat pump and to continuously accumulate in the hot water tank to continuously maintain the hot water filled in the hot water tank Since it can be heated by heating, there is no fuel consumption in heating the hot water supply, and the hot water can be discharged directly to the water valve according to the season or flowed into the individual boiler, so it can be used for convenience and individual boiler. It can reduce the gas consumption of hot water, and the hot water of the preheated state by the hot water tank flows through the hot water supply pipe or branch pipe, so the dissolved oxygen content of the preheated water is lower than the cold water, which can reduce the corrosion rate of the pipe. When the water is discharged through the water valve, warm water can be supplied from the beginning. To supply hot water boiler only effects that you can save water compared to discard all of the cold water until the initial warm you would.
